Best answer Biomass in terms of fresh weight shows variations in weight due to seasonal moisture differences whereas the biomass in terms of dry weight remains unaffected by such seasonal moisture variations. Therefore, the measurement of biomass in terms of dry weight is considered more accurate than fresh weight.
Why is biomass measured in terms of dry weight instead of fresh?
Best answer Biomass in terms of fresh weight shows variations in weight due to seasonal moisture differences whereas the biomass in terms of dry weight remains unaffected by such seasonal moisture variations. Therefore, the measurement of biomass in terms of dry weight is considered more accurate than fresh weight.
Which measurement is more accurate in terms of biomass?
Measurement of biomass in terms of dry weight is more accurate. Why? Dry weight is the exact mass of any body which remains constant but wet mass or body with water have variable mass as per water present in the body.
Why is dry mass more accurate than wet mass?
Measuring dry mass is more accurate than measuring wet mass. This is because water content can change depending on conditions. A plant may contain less water if the weather has been hot and dry.
What is the moisture content of a biomass?
Dry weight of a biomass does not include any amount of water or moisture content in it. The moisture content of a biomass may vary depending upon environmental or physiological conditions.
Why is dry mass used to measure biomass?
Biomass is the total mass of living material measured over a particular area. Because all living things contain water (fresh mass) and the percentage of water can vary widely from species to species, biomass is calculated as a dry mass.
Which of the following will be more accurate weight of biomass?
Measurement of biomass in terms of dry weight is more accurate.
Why should dry weight rather than wet weight be used to determine biomass?
Dry weight will provide a precise measurement of biomass eliminating fluctuations caused by water content. Plant total biomass can be directly related to our plant performance as a response to photosynthetic capacity, nutrition, environmental conditions, and more.
Which is more reliable basis for expressing results in plant Analysis fresh weight or dry weight?
Measuring dry weight: Since plants have a high composition of water and the level of water in a plant will depend on the amount of water in its environment (which is very difficult to control), using dry weight as a measure of plant growth tends to be more reliable.
What is the disadvantage of using dry mass is measurement of growth?
Disadvantage : Not accurate enough because can measure in only one dimensions and measurement cannot truly represent its growth.
Why is pyramid of biomass in sea generally inverted explain?
The graphical representation of the pyramid of biomass is the biomass sequence wise person unit area of different trophic levels. The pyramid of biomass in the sea is inverted because the amount of biomass is least at the base of the pyramid and the amount of biomass is maximum at the apex of the pyramid.
Why is dry mass more reliable?
Dry mass is a more reliable measure of mass than fresh mass because the former excludes the fluctuating water concentrations in the biological material measured which is present in the latter.
What is dry weight in biomass?
“Biomass,” and “Wet mass”) Dry weight refers to the weight of animal tissue after it has been dried in an oven at 65°C until a constant weight is achieved. Dry weight represents total organic and inorganic matter in the tissue. (See also “Wet weight”).
What is dry biomass?
The dry biomass mainly refers to completely removing moisture content or biomass produced without water and includes only dry organic matter, including crops waste, dried plant leaves, shoots, barks, twigs, etc.
How is dry biomass measured in plants?
There are many methods of determining plant biomass, but perhaps the most common method used for rangeland and pasturelands is clipping and weighing. Clipping techniques involve the removal of all above- ground herbaceous vegetation within a sample plot and measuring its dry mass (air or oven-dried vegetation).
Why does the value of fresh and dry weight change in a plant?
The value will be changed because of water evaporation. In my opinion, this is due to the differing physiological composition of the shoot versus the root tissue. Also, the roots may be suberized, while the shoot part of the plant is more succulent. Almost all the plants have 75-80%: moisture.
